Transmigrated as Dekisugi: I Rewrite Doraemon

Chen Xing transmigrates into the world of Doraemon and becomes Hidetoshi Dekisugi, the top student everyone admires. His body has changed, but his mind is still that of a modern young man. Burdened with a perfect image, he lives through the familiar routine of endless homework and Gian beating up Nobita every day.

He looks flawless on the surface, but danger lurks beneath. One exam mistake could expose his identity. He has to help Nobita without arousing suspicion, quietly keeping everything under control without breaking the persona everyone knows.

He unexpectedly gains the golden finger "Thought Replay," which lets him revisit his memories as often as he likes and precisely analyze any phenomenon. Gaps in his knowledge, the truth behind events, and other people's patterns of behavior can all be deduced and reconstructed.

With the System's help, he quickly masters all of Dekisugi's knowledge and can also foresee dangers and solve difficult problems. A slip of the tongue about homework, an accident with the shrinking light, and a quicksand trap are all secretly dealt with.

While everyone else panics, he has already seen through the truth. Nobita relies on Doraemon to save the day; he uses Thought Replay to turn the tables. He secretly lays plans when Shizuka is in danger and deftly counters Gian's bullying, while remaining the calm top student in public.

In the future, he will use modern thinking to solve the mystery of dorayaki, reverse distortions in time and space, save the dinosaurs from extinction, and mend fractured memories. In the end, he will uncover the System's ultimate truth and become the true hero who protects childhood.
